I've set up a couple of templates with gestures. This is a really great feature.
However, it only seems to recognise one of them. No matter how distinct I make the gestures, it always inserts the first one in the list.

I've tried deleting the templates, deleting the gestures file and starting again, but no luck.

The touchscreen doesn't work, but I have rebooted into recovery and done a backup. When my replacement arrives, I can just root it, then copy the backup over and do a restore, right? Any issues with that?

Can someone please advise where the backup file is stored, so I can pull it from adb (this is the biggest problem with no removable storage!)

I've got something similar. The phone appears to be off, and I can't tell whether it is or not. I have to hold down the power for several seconds, which forces it to turn off and then I can turn it on again.

Mine only seems to do it very intermittently. It could do it 2 or 3 times in one day, and then could go a week without it happening.

That's definitely it. I deleted the old backups through the recovery menu, rebooted, and now I have 9.6GB available.
I don't know why I couldn't browse to the backup files using file explorer, but at least I have got to the bottom of my first issue.

As to why I couldn't restore from the most recent backup I don't know.

OK, this is odd, and a bit worrying. I went to restore from a previous backup, and got MD5 mismatch error.
I browsed to sdcard/clockworkmod and there is nothing in there. Despite this, when I go to backup and restore from the recovery menu, it lists my previous backups.

Looks to me as though it is creating the backups and putting an entry somewhere but then not actually saving them in sdcard/clockworkmod

That's done something very odd to my internal storage. It's showing as just 1.4GB available, but when I add up all of the elements below it only adds up to 2GB. My Nexus is showing as 12.92GB total space, so no idea where the missing space is. Apps is only 720MB
